3 Claims. (Cl. 20--12) This invention relates to sash guides for double-hung sash windows and, in particular, to resiliently-mounted sash guides for removable sash windows.

One object of this invention is to provide a resilientlymounted sash guide installation for sliding sash windows, wherein the sash guide is resiliently supported by a simplied spring mounting of inexpensive yet strong construction which is quickly and easily installed in the side jambs of a window frame.

Another object is a provide a resiliently-mounted sash guide installation of the foregoing character which is quickly and easily adjusted, after installation, merely by tightening or loosening the same screws which secure it to the side jamb of the window frame.

Another object is to provide a resiliently-mounted sash guide installation of the foregoing character wherein the resilient action is provided by leaf 4springs secured at intervals along the sash guide and having their opposite' ends yieldingly engaging the adjacent side jamb of the window frame.

Another object is to provide a resiliently-mounted sash guide installation of the foregoing character which is equally well adapted to sliding sash windows of metal or wood construction. j

Other objects and advantages of the invention will become apparent during the course of the following description of the accompanying drawings, wherein:

Figure 1 is a horizontal section through a double-hung removable sliding sash window installation utilizing a resiliently-mounted sash guide construction according to one form of the invention, employing a metallic doubleglazed sash, taken along the line 1*-1 in Figure 2;

Figure 2 is a fragmentary vertical section taken along the line 2-2 in Figure 1;

Figure 3 is a fragmentary longitudinal section taken along the line 3 3 in Figure 2, at right angles thereto;

Figure 4 is a fragmentary side elevation, looking in the direction of the arrows 4 4 in Figure 2;

Figure 5 is a fragmentary perspective View of the spring anchorage and central portion of the leaf spring employed in the resiliently-mounted sash guide of Figures 1 to 4 inclusive; and

Figure 6 is a fragmentary horizontal section similar i to the lower left-hand corner of Figure 1, but showing the invention applied to a wooden removable sliding sash window.

Referring to the drawing in detail, Figure 1 shows diagrammatically a window frame, generally designated 10, `of the double-hung removable sliding sash type equipped with resiliently-mounted sash guide installation, generally designated 12, according to the present invention, as applied to double-glazed metal sliding sash, generally designated 14, equipped with a spring sash balance, generally designated 16. The window frame 10 hasside jambs 18 with elongated vertical recesses or channels 20 in which the sash guides 12 are seated so that their front Walls are substantially flush with the 2,856,648 Patented Oct. 21, 1958 Nce walls 38 parallel to one another but set farther apart4 than the forward side walls 34 and interconnected at their rearward edges by a rearward wall 40. The rearward flanges 28 are provided with half-round notches or half holes 41 aligned with the holes 32. The side walls 38 and rearward wall 40 form an elongated spring chamber or channel 42 for accommodating the elongated helical tension spring 44 of the spring sash balance 16. The latter is conventional and its details are outside the scope of the present invention.

From Figures 1 and 2 it will be observed that the rearward wall 40 is set forth from the plane of the rearward flanges 28 of the outer side walls 26 by an amount equal substantially to the thickness of a spring mounting or anchorage plate, generally designated 50 (Figure 5) adapted to hold a leaf spring, generally designated 52. The spring anchorage plate 50 is mounted transversely in the space 54 (Figure 2) between the ilanges 28 and rear wall 40 (Figures 1 and 2) so as to be retained firmly in position, with its opposite ends 56 engaging or immediaiely adjacent the inner surfaces of the outer side walls 26 so as to prevent twisting or turning of the anchorage plate 50 relatively to the sash guide 24. The spring anchorage plate 50 is provided with screw holes 58 aligned with the screw access holes 32 and adapted to receive the Shanks of screws 60 threaded into the side iambs 18 of the window frame 10. The screw access holes 32 are of sufficiently large diameter to pass the heads of the screws 60, the Shanks of which engage the notches or half holes 41 in the rearward edge ilanges 28 in order to prevent sidewise shifting of the sash guide 24 in their recesses 20 in the side jambs 18.

Each screw anchorage plate 50 and its associated leaf spring 52 collectively forms a resilient sash guide mounting, generally designated 62, shown for the most part in Figure 5. These units 62 are mounted at spaced intervals along each sash guide 24 so as to resiliently support the latter throughout substantially its entire length. Each anchorage plate 50 at approximately its center is provided with a pair of spaced struck-up lugs 64 with side walls 66 disposed parallel to one another and spaced apart at approximately the width of the leaf -spring 52 and having edge ilanges 68 bent toward one another so as to retain the leaf spring 52 in position (Figure 5). The leaf springs 52 are of generally arcuate shape with approximately the form of an archers bow (Figure 2), having a central arcuate portion 70 and reversely-bent opposite ends 72 to provide a smooth bearing engagement with the adjacent surface 74 of the side jamb 18. The lugs 64 are struck up out of approximately rectangular slot-s 76 (Figure 4) which are spaced apart from one another by a bridge portion 78 providing an abutment against which the leaf spring 52 is held by the flanges 68 of the lugs 64.

The sash 14 is conventional and the double-glazed form shown in Figure l consists of metallic border members 80 having ribs or tongues 82 extending into the entrances or openings 36 for guidance purposes, assisted by the surfaces 84 on either side thereof engageable with r ases-,64s

generally designated 92, shown in Figure 6 is similar in construction, purpose and operation to that of Figures 1 to 5 inclusive, .diifering only in the details of construction necessary to adapt it to a wooden sliding sash window, generally designated 94. The latter has Wooden border members 96 which are rabbeted as at 9S to receive the window pane 100 held in place by the usual putty or other glazing material 102. The side border members 96 also have tongues or ribs 104 which engage the outer channel 106 formed in the sash guide, generally designnated 108.

The sash guide 108, like the sash guide 24, has outer side walls 110 with rearward edge flanges 112, front Walls. 11,4 with screw access holes 116, forward spaced side walls 118 separated from more closely spaced rearward side walls 120 by reversely-bent portions 122 separated by a narrow gap 124. The rearward side walls 120 are inten connected by a rearward wall 126 to form a spring chamber 128 for the conventional spring sash balance 130. The resilient sash guide mounting employed in Figure 6 is substantially the same as that employed in Figures l to inclusive, and therefore is designated With the same general reference numerals 62 and its individual parts and portions are designated with the same reference numerals as the corresponding parts shown, for example, in Figure 5. The screws 60 are employed in a similar manner to hold the spring anchorage plate S2 and also to provide an adjustment, as described below in connection with the operation of the invention.

The operation of the resiliently-mounted sash guide installation 12 and of the modified sash guide installation 92 is similar, hence asingle description will suiiice for both, as applied, for example, tothe sash guide installation 12. From Figure l it will be observed that each sash 14 is supported by a pair ofsash guide installations 12, both parallel to one another on` opposite sides of the window frame adjacent opposite window jambs 18. Let it be assumed that the sash 14 is in the position shown in Figure 1 and that it is to be removed for cleaning or other purposes. To do this, the operatorrgrasps the sash 14 in any convenient location andpushes it sidewise in either direction, for example, to the left'in Figure l. This action, by the engagement of the surface 84V of the border member 80 with the front wall of the sash guide 24 pushes the latter to the left further into the recess 20, compressing the leaf spring 52 by the transfer of lateral motion to it through the anchorage plate 50 seated in the sash guide 24. As the sash guide 24 and spring mounting 62 move to the left, they areguided by the screws 60.

When the sash 14` has been moved far enough to the left, for example, to cause the tongue 82 on the opposite side thereof to clear theopening 34 in the opposite sash guide installation 12 (Figure l), the right-hand side of the sash 14 can be swung outward clear of the front walls 30 of the right-hand sash guide 24, whereupon the lefte;

hand side of the sash 14` can also be pulled out of its corresponding sash. guide 24. The leaf springs 52 push the sash guides 24 outwardaas the sash 14 is removed, until halted by the engagement of the anchor plates S0 with they heads of the screws 60. The positions ofthe parts with the sash removed, are as shown in the upper half of Figure l.

To re-insert the sash 14, the foregoing procedure is reversed, one edge of the sash 14 being inserted in its particular sash guide 24. Lateral pressure is then appliedl to the sash 14 to push the already engaged sash guide 24 inward so that the opposite edge of the sash 14 will clear the as yet unengaged sash guide 24, whereupon the sash 14 is released and its free tongue 82 arrives opposite the opening 36 in the unengaged sash guide 24. The springs 52 behind the engaged and displaced sash guide 24 then push the sash 14 into engaging position with the opposite sash guide and the installing operation is thus completed.
